Method for anodic polishing of surfaces of intermetallic niobium compounds according to and niobium alloys

摘要

The surface of an intermetallic niobium compound or niobium alloy to be polished is electrically shunted across a niobium part and immersed in electrolyte together with the latter permitting relatively thick surface layers of niobium compounds of high quality which are used for superconducting a-c apparatus to be produced.
